I have two tables master and temp

master table contains the sp_no, range of srl_no.
Temp table contains srl_no and id, now I have to write a script which will fill all the relevant spo no in the temp table..

that is:
master
sp_no   start_srl_no   end_srl_no
1001    101            150
1005    151            180
1010    181            215


temp
srl_no      spo_no
101         1001(to be filled)
102         1001
103         1001
.
.
.
150         1001
151         1005
152         1005

What is your problem writing this query?
Use SQL*Plus and copy and paste what you already tried.

Before please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter), use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version with 4 decimals.

Regards
Michel

I cannot provide direct answers as this is against forum guidelines, however, I can give you hints to help you get started. You need to use row generator technique for this. Search this forum for the same

Why a row generator?

I was thinking of generating rows for the maximum difference between end serial no and start serial no. Use this to cartesian join with main table and finally add row_number() over to the start serial no and stopping when this equals end serial number.

Ofcourse there may be other method as well but this one came to mind immediately.

Unless I misunderstood, he said that "Temp table contains srl_no and id" and he just want "to write a script which will fill all the relevant spo no in the temp table", which row generator is needed to fill a column? Just BETWEEN is needed.

Michel

I just said there may be other methods. may be using plsql pipelined function or model clause. I am not very conversant with model clause so I cannot be sure on that.

His temp table need to be filled from start serial number to end serial number. In his example in case of sp_no 1001 which has start serial number as 101 and end serial number as 150 he wants to insert seperate rows in the temp table begining at 101 and ending at 150. I would be really curious to know on inserting these rows using between clause.

It is already filled, read again "Temp table contains srl_no and id".

You don't need to insert anything the question is: "fill all the relevant spo no in the temp table." No Insert, only update.

You are correct Michel. I kind of read the message incorrectly. OP just needs to bring spo_no in temp table which is an update not an insert.
